EquipmentContainer that will typically include conductors, energy consumers, transformers and transformer windings, switches, shunt compensators, etc., likely at different voltages. Circuit extends from a substation to a set of open points (radial circuit), or to a second substation (looped circuit). It generally starts with a switching device, located in a substation. Membership in a Circuit is based on the nominal or design system configuration, but the electrical connectivity will change during switching operations.EquipmentContainer that will typically include conductors, energy consumers, transformers and transformer windings, switches, shunt compensators, etc., likely at different voltages.
